Keywords: no waste oil, semi-permanent use of engine oil, emulsion of oil in water, waste oil from compressors, fertilizer plants, slip of oil, pollution of river and coastal sea. 1 Introduction The authors have been engaged in developing a system of technologies for provision of clean fuel oil, clean lubricating oil (LO) [1], and clean water [2].

Oil Test Kits | Lubricating On-site Oil Sampling Equipment .

These oil test kits will identify most major problems in time to limit major damage. They will give you comfort that the oil is fit for use and system free of major contamination. The ability to test On-Site at the point of use enables you to conduct oil analysis quickly and easily.


The system oil in large medium and low speed diesel engines is intended to be in use for a long time. The normal case is that the lubricating oil stays in the engine without replacement. Only the loss of oil, e.g. consumption during operation and loss of oil in the cleaning system, is compensated for by the topping up the volume with new oil.

Lessons Learnt: Defective lube oil cooler causes pollution .

A diving inspection confirmed the presence of oil in the discharge water when the lube oil cooling water pump was running. Analysis. The main engine lube oil cooler was found to be leaking at the sea water outlet flange and collected water showed signs of oil contamination.

Lubricating Oil - an overview | ScienceDirect Topi

Lubricating oil (LO) and control oil systems are covered in API 614 (1999). It is noted that other API machinery-specific standards reference API 614 for the LO system requirements. API 614 is a generic specification for all LO and control oil systems, but a couple of important requirements and issues should be emphasized:

Predictive Equipment Maintenance - Spectro Scientif

of adhesive wear. It is necessary to keep the lubricating oil clean and dry at all times. To keep oil fit for use, oil conditions are to be monitored regularly to make sure the oil is used within its performance specification. A well balanced oil analysis program shall monitor machine wear condition, oil contamination and oil degradation.

What Oil Analysis Tests Tell Us - machinerylubrication.c

The AN test is performed on nonengine oil samples and is used to quantify the acid buildup in these oils. An increased AN is a result of oxidation of the oil, perhaps caused by overheating, overextended oil service, or water or air contamination. Components within refrigeration systems are particularly susceptible to acid attack.

Contaminated Lube Oil Caused Engine Damage - mfame.gu

As a preliminary investigation, the lube oil cooler and the coolant temperature was checked on the local temperature gauges. The engineer on watch reported that there was an abnormal level in the sump tank and the cooling water expansion tank had lost water. Cooling water had got into the lubricating oil sump and contaminated the lube oil system.
